Installation and Operation
1. Substation speaker
2. Substation MIC
3. Substation housing
4. Substation alarm key (call)
Ⅱ. Technical Parameters:
Working voltage: DC10-22V
Substation dimension: 140x138x55mm(LxWxH)
Max working voltage: 100mA
Output power of substation speaker: 800mW
Ⅲ. Installation and Operation:
1. Substation coding:
Five binary coding switches are installed in the back of the
substation, it means 1, 2, 4, 8, 16 in “ON” position. E.g.: code in
no. 3 substation is 1+2, switch positions of 1 and 2 are placed in
On position. E.g.: code in no. 14 substation is 2+4+8, switch
positions of 2, 4 and 8 are placed in On position. Code in no. 19
substation is 1+2+16, switch positions of 1, 2 and 16 are placed in
On position. After the coding, the master station will confirm
2. Connecting mode of substation:
Connect 1, 2, 3, 4 in the binding post in the back of substation to
1, 2, 3, 4 in the binding post of master station via 4-wire.
After connecting with the master station, turn on the power of
master station, if the alarm indicator light in substation blinks in
several seconds, it means the substation is in normal state. If not,
it means the substation is out of control.
4. Recording method:
Output sound signal from the record output port REC+ and REC- in
the binding post of substation, in order to record in the
substation. The substation can be used as a monitor head.
5. Connecting method of door lamp:
Connect the positive pole of line behind the door lamp to the M+ in
the binding post of substation, and negative pole to COM.
6.Alarm and Intercoms of Substation:
Depress the Alarm key in the substation panel, the master station
will have a music prompt, when the master station selects the
substation, the intercom is available. There is a plug of handheld
alarming machine in the back of substation, when the substation or
handheld alarming machine alarms to the master station, the door
lamp will blink.
7. Releasing Alarm:
If the substation has sent out a call and you want to release the
alarm, press the external release alarm key.
1. pay attention to the correct installation of ground wire (line
4) when connecting lines with substation. Any incorrect operation to
connect a ground wire (line 4) of the substation in one bus will
cause that any substation in corresponding 1-20 call master station
will be difficult or fail to select.
